5.4 Multiscale modeling of multidirectional soft
tissues
In the case of multidirectional tissues (e.g., arterial walls), previous compu-
tational and analytical homogenization schemes can be simply generalized
by computing the equivalent mechanical response for each layer, wherein a
regular unidirectional ber arrangement can be postulated, and introducing
